Class JCEKeyGenerator.DESede

java.lang.Object

javax.crypto.KeyGeneratorSpi

org.bouncycastle.jce.provider.JCEKeyGenerator

org.bouncycastle.jce.provider.JCEKeyGenerator.DESede

Enclosing class:

JCEKeyGenerator

public static class JCEKeyGenerator.DESede
extends JCEKeyGenerator

DESede - the default for this is to generate a key in a-b-a format that's 24 bytes long but has 16 bytes of key material (the first 8 bytes is repeated as the last 8 bytes). If you give it a size, you'll get just what you asked for.
